Allergic vasculitis

Vasculitis - allergic; Hypersensitivity vasculitis; Cutaneous leukocytoclastic vasculitis

Last reviewed: April 20, 2013.

Allergic vasculitis is an extreme reaction to a drug, infection, or foreign substance. It leads to inflammation and damage to blood vessels of the skin.

Causes, incidence, and risk factors

Allergic vasculitis is caused by an allergic reaction to a drug, an infection, or other foreign substance. It most often affects people older than age 15.

Often, the cause of the problem cannot be found even with a careful medical history.

Allerigic vasculitis may look like necrotizing vasculitis, which can affect blood vessels around the body.

Symptoms

Signs and tests

The doctor will base the diagnosis on symptoms and the appearance of how your skin looks after you take a certain medicine or are exposed to a foreign substance (antigen).

Results from an ESR test may be high. Skin biopsy shows inflammation of the small blood vessels. You may also have other tests to detect this condition.

Treatment

The goal of treatment is to reduce inflammation.

Your health care provider may prescribe aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), or corticosteroids to reduce inflammation of the blood vessels. (DO NOT give aspirin to children except as advised by your health care provider.)

Your doctor may tell you to stop taking a medicine that could be causing this condition. Do not stop taking any medicine without first talking to your doctor.

Expectations (prognosis)

Allergic vasculitis usually goes away over time. The condition may come back in some people.

People with ongoing vasculitis should be checked for necrotizing vasculitis.

Complications

Calling your health care provider

Call your health care provider if you have symptoms of allergic vasculitis.

Prevention

Do not take medicines which have caused an allergic reaction in the past.
